Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] As Figures 1-7 shown, the present invention provides a flipping device, including a support bottom plate 1. Both side edges of the upper part of the support bottom plate 1 are fixedly connected with Y-shaped support frames 2. The mounting holes at the four corners of the support bottom plate 1 can play a role in assembly and installation, so that the support bottom plate 1 and the Y-shaped support frames 2 can support and erect the polygonal frame 4, thereby enabling the polygonal frame 4 to maintain good stability;

[0026] A polygonal frame 4 is provided between the two Y-shaped support frames 2. Splash-proof baffles 5 are fixedly connected to the polygonal frame 4 on the side edges of the opening. The splash-proof baffles 5 can play a shielding role during spraying, preventing the paint from splashing outwards when spraying metal parts, and at the same time avoiding excessive spraying of other metal parts, resulting in uneven paint thickness;

[0027] Moreover, a driving device 9 is installed between the polygonal frame 4 and the Y-shaped support frame 2 fixedly installed below the fine-tuning component 6 on the board surface. The driving device 9 includes a driving motor 91, which is fixedly connected to one side of the Y-shaped support frame 2 close to the polygonal frame 4. The output shaft of the driving motor 91 is fixedly connected with a second driving gear 92, and the second driving gear 92 is meshed with a driving gear ring 93. The second driving gear 92 can be meshed and driven with the driving gear ring 93 to play a role in power transmission. Then, through the drive of the driving motor 91, the second driving gear 92 drives the driving gear ring 93 to drive the third bearing 94 to rotate, so that the polygonal frame 4 can control the circumferential movement of multiple turnover frames 12, and at the same time, the positions of the turnover frames 12 can be alternately switched, thereby facilitating the cyclic spraying operation, improving the processing efficiency, and meeting the requirements of automated processing operations;

[0028] The driving gear ring 93 is rotatably connected to the outer ring of the third bearing 94, and the polygonal frame 4 is rotatably connected to the outer ring of the third bearing 94. The inner ring of the third bearing 94 is fixedly connected with a support shaft 95, and the support shaft 95 is fixed on the Y-shaped support frame 2, which can support the third bearing 94 and ensure the stable rotational movement of the driving gear ring 93;

[0029] The support shaft 95 is fixedly installed on one side of the Y-shaped support frame 2 close to the polygonal frame 4. A turnover frame 12 is correspondingly arranged in each opening of the polygonal frame 4. An elastic rolling clamping component 13 that is slidably matched with the arc-shaped plate 67 is assembled and installed on one side of the turnover frame 12. The elastic rolling clamping component 13 includes a sliding ball 136. Using the sliding ball 136 has good rolling performance. On the one hand, it can reduce the friction with the arc-shaped plate 67, making the sliding ball 136 move smoothly. On the other hand, it can ensure the smoothness of the whole operation;

[0030] A movable rod 135 is fixedly connected to the opposite side of the sliding ball 136 and the third rotating shaft 138. One end of the movable rod 135 far from the sliding ball 136 is fixedly connected with a fixed clamping plate 131. A first rubber layer 133 is fixedly connected to the opposite side of the fixed clamping plate 131 and the second rubber layer 16. The first rubber layer 133 and the second rubber layer 16 can not only increase the anti-slip property when clamping metal parts, improve the firmness of clamping the metal parts to be sprayed, but also have good softness, so as to protect the metal parts;

[0031] Both end faces of the fixed clamping plate 131 are fixedly connected with guide sliders 134 that are slidably engaged with the guide chutes 17. The two guide chutes 17 are opened on the two cross beams inside the polygonal frame 4. The guide chutes 17 can guide the guide sliders 134, enabling the guide sliders 134 to slide smoothly along the guide chutes 17, so that the fixed clamping plate 131 can move smoothly;

[0032] Between the side of the fixed clamping plate 131 away from the first rubber layer 133 and the longitudinal beam of the polygonal frame 4, both ends of the return spring 132 are fixedly connected. The elastic tension of the return spring 132 can drive the fixed clamping plate 131 to reset, enabling the fixed clamping plate 131 to automatically release the fixation of the metal part, thus facilitating the automatic discharging of the metal part and facilitating the processing operation of the metal part;

[0033] The return spring 132 is sleeved outside the movable rod 135. The movable rod 135 is slidably connected in a matching movable opening 139. The design of the movable opening 139 can ensure the smooth passing of the movable rod 135, enabling the movable rod 135 to pass through smoothly and be connected to the fixed clamping plate 131, so that the movable rod 135 can smoothly control the movement of the fixed clamping plate 131;

[0034] And the movable opening 139 runs through and is opened on the third rotating shaft 138. The third rotating shaft 138 is rotatably connected in the fifth bearing 137. The fifth bearing 137 can support the third rotating shaft 138 and at the same time enable the third bearing 94 to rotate smoothly, so that the turning frame 12 can rotate smoothly;

[0035] The fifth bearing 137 is embedded and installed in the polygonal frame 4. The end of the arc-shaped plate 67 is designed with an obtuse arc surface. Through the setting of the obtuse arc surface at the end of the arc-shaped plate 67, the sliding ball 136 can smoothly contact the arc-shaped plate 67 and at the same time can push the movable rod 135 to move along with the thickening of the arc-shaped plate 67, enabling the movable rod 135 to push the fixed clamping plate 131 to complete the automatic fixation of the metal part;

[0036] And the arc-shaped plate 67 is assembled on the plate surface fine-tuning assembly 6. The plate surface fine-tuning assembly 6 includes a cross-shaped fixing frame 61. The cross-shaped fixing frame 61 is fixedly installed on the top of the Y-shaped support frame 2. The cross-shaped fixing frame 61 can install and fix the height of the threaded sleeve 62. The threaded sleeve 62 is embedded and installed on the longitudinal beam of the cross-shaped fixing frame 61. A driving screw 64 is threadedly connected in the threaded sleeve 62. The rotation of the driving screw 64 can be screwed in through the threaded cooperation with the threaded sleeve 62. Then, through the first bearing 33, the position of the arc-shaped plate 67 can be finely adjusted, so as to meet the positioning requirements of metal parts of different sizes;

[0037] The driving screw rod 64 is rotatably connected in the second bearing 63. The second bearing 63 is installed on the arc-shaped plate 67. The second bearing 63 can not only ensure the stable rotation of the driving screw rod 64, but also play a role in connecting the driving screw rod 64 and the arc-shaped plate 67, enabling the driving screw rod 64 to smoothly control the movement of the arc-shaped plate 67;

[0038] One end of the driving screw rod 64 away from the second bearing 63 is fixedly connected with an operating handwheel 65. Guide support rods 66 are slidably connected in the two guide holes of the cross beam of the cross-shaped fixing frame 61. One ends of the two guide support rods 66 are fixedly connected to the arc-shaped plate 67. The design of the operating handwheel 65 can provide a force application point for the staff, facilitating the staff to control the rotational movement of the driving screw rod 64 through the operating handwheel 65. At the same time, the guide support rods 66 can smoothly slide in the cross beam of the cross-shaped fixing frame 61, avoiding the problem of the arc-shaped plate 67 rotating, and further avoiding the problem that the arc-shaped plate 67 is misaligned with the sliding ball 136, resulting in the inability to achieve fixation subsequently;

[0039] A transmission component 3 is assembled and installed on one side of the turnover frame 12 away from the elastic rolling clamping component 13. The transmission component 3 and the elastic rolling clamping component 13 are both assembled on the polygonal frame 4. The transmission component 3 includes a first driving gear 31. The first driving gear 31 is embedded and installed at one end of the first rotating shaft 32 away from the turnover frame 12. The first rotating shaft 32 is rotatably connected in the first bearing 33. The first bearing 33 supports the first rotating shaft 32, and at the same time, the first bearing 33 can ensure the smooth rotation of the first rotating shaft 32, enabling the first driving gear 31 to move smoothly;

[0040] The first bearing 33 is embedded and installed in the polygonal frame 4. One end of the first rotating shaft 32 away from the first driving gear 31 is fixedly connected to the turnover frame 12. A second rubber layer 16 is fixedly connected to a longitudinal beam in the inner cavity of the turnover frame 12 and the same as the first rotating shaft 32. A limit card slot 14 engaged with the rubber bump 15 is opened on each opening side wall of the polygonal frame 4. The rubber bump 15 has elastic deformable force, enabling the rubber bump 15 to deform and break out of the limit card slot 14 under the action of an applied force, so that the turnover frame 12 can move smoothly. After the turnover frame 12 is turned over, the rubber bump 15 correspondingly snaps into the limit card slot 14, enabling the rubber bump 15 to play a role in shaping the turnover frame 12 and preventing the turnover frame 12 from turning over randomly, which may easily cause the metal parts to turn over and affect the spraying operation;

[0041] Moreover, every two rubber bumps 15 are fixedly connected to the same flipping frame 12, and multiple first driving gears 31 are arranged in a circle. One of the first driving gears 31 meshes with the driving rack 18. The driving rack 18 is arc-shaped, and the arc length of the driving rack 18 is 1 / 2 of the circumference of the first driving gear 31. The arc length of the driving rack 18 being half of the circumference of the first driving gear 31 enables the first driving gear 31 to smoothly flip 180 degrees to drive the metal part to complete the turning-over process. Furthermore, the driving rack 18 and the gear transmission can complete the automatic turning-over operation of the metal part, facilitating the processing of the metal part and improving the processing efficiency at the same time;

[0042] A fixing plate 8 is fixedly connected to the lower part of the driving rack 18. The fixing plate 8 is fixedly installed above the second rotating shaft 10, and the second rotating shaft 10 is fixedly connected to one side of the Y-shaped support frame 2 away from the arc-shaped plate 67. The second rotating shaft 10 is embedded in the second bearing 63, and the polygonal frame 4 is rotatably connected to the outside of the second bearing 63. The fixing plate 8 can play a role in connecting the second rotating shaft 10 and the driving rack 18, and thus can fix the position of the driving rack 18. Moreover, the driving rack 18 is designed in an arc shape, enabling the gear to smoothly mesh with the driving rack 18 during movement. The second rotating shaft 10 can support the second bearing 6, enabling the second bearing 63 to maintain correspondence with the center of the third bearing 94. At the same time, the second bearing 63 can support one end face of the polygonal frame 4 to keep the polygonal frame 4 stably erected. Meanwhile, the outer ring of the second bearing 63 can ensure the smooth rotational movement of the polygonal frame 4.

[0043] The working principle of the present invention:

[0044] During adjustment, first rotate the operating handwheel 65, causing the operating handwheel 65 to drive the driving screw 64 to rotate, enabling the driving screw 64 to threadedly advance in the threaded sleeve 62, so that the driving screw 64 can control the fine adjustment of the arc-shaped plate 67 through the second bearing 63. At the same time, the sliding ball 136 can maintain contact with the arc-shaped plate 67, thereby meeting the size requirements of the metal part;

[0045] Then control the driving motor 91 to operate, so that the driving motor 91 drives the second driving gear 92 to rotate, so that the second driving gear 92 drives the driving gear ring 93 to rotate, so that the driving gear ring 93 drives the third bearing 94 to rotate, so that the outer ring of the third bearing 94 drives the polygonal frame 4 to rotate, so that the polygonal frame 4 drives the turnover frame 12 and the elastic rolling clamping assembly 13 to rotate. When the turnover frame 12 is transferred from below to the front side, the metal part to be sprayed can be placed in the turnover frame 12 at this time. When the sliding ball 136 moves upward and contacts the end face of the arc-shaped plate 67, since the end face of the arc-shaped plate 67 gradually thickens, the sliding ball 136 can push the movable rod 135 to move while rolling on the end face of the arc-shaped plate 67, so that the movable rod 135 pushes the fixed clamping plate 131 to move, so that the fixed clamping plate 131 stretches the return spring 132. At the same time, the fixed clamping plate 131 approaches the metal part and can complete the clamping and fixing of the metal part. At this time, the metal part to be sprayed is located above and below the spraying device. At this time, the metal part can be sprayed by the spraying device. During spraying, the turnover frame 12 below is turned over to the front again, and the metal part to be sprayed is placed again. After the metal part above is sprayed;

[0046] Then the driving motor 91 continues to operate, so that the sliding ball 136 can push the fixed clamping plate 131 through the movable rod 135 again to clamp and fix the metal part to be sprayed. The metal part after single-sided spraying is turned to the upper side of the rear. When the first driving gear 31 meshes with the driving rack 18 and drives, the first driving gear 31 can rotate, so that the first driving gear 31 drives the first rotating shaft 32 to rotate, so that the first rotating shaft 32 drives the turnover frame 12 to rotate. Since the arc length of the driving rack 18 is 1 / 2 of the first driving gear 31, the first driving gear 31 can drive the turnover frame 12 to turn 180 degrees through the first rotating shaft 32 when it rotates half. At this time, the turnover frame 12 can drive the metal part to complete the turning operation smoothly. Then the other side of the metal part can be sprayed by the spraying device. After the spraying is completely completed, the driving motor 91 continues to operate, so that the polygonal frame 4 moves again, so that the metal part after single-sided spraying on the other side can be turned over and sprayed again. The metal part after spraying is located at the rear. At the same time, the sliding ball 136 is separated from the arc-shaped plate 67. At this time, the elastic force of the return spring 132 can drive the fixed clamping plate 131 to reset, so that the first rubber layer 133 is separated from the metal part, so that the sprayed metal part can automatically complete the blanking operation. This method can be used for cyclic turning and spraying processing operations.
